You can - like me - use gvim, like replacement of internal AutoCad MTEXT editor. You need switch variable MTEXTED to "gvim" (or maybe fullpath, something like "c:\vim\vim60aq\gvim" ), and to your _vimrc you can put line:

autocmd BufRead,BufNewFile *.tmp source c:\vim\aacad.vim

And when you edit MTEXT in acad, menu AutoCad will be for your use in gvim (only in INSERT and VISUAL mode)

NOTE: Only I can't start gvim like gvim -y (for any other person, not so accustomed vith gvim) or start gvim from gvim.lnk or gvim.bat (I'am using windows95) and automatic skip to INSERT mode -latest word star, on end of script- is without functionality(?) Maybe someone advise me??
